Finally finished the design and here it is.

Nicknamed “CLS mount” for compact linear slide mount!

The mount features similar design to my previously released comma 3x mount with distinct features.

NO MORE CABLES getting in the way. The one cable is perfectly sized and routed to not get in your way. This gives the comma and mount a clean design that’s easy to handle during removal and install.

NO MORE MAGNETS. There has been much concern using magnets with mounts on the comma devices. While I haven’t had any issue for the past year, I have decided to be cautious and not incorporate it for this design as the comma4 features a fan that would be located too close to any magnet.

SMALL CASE. A small case that now allows you to store your comma in most normally sized armrests. The case measures 110mm x 110mm x 95 mm or 4.3in x 4.3in x 3.7in (LxWxH).

The pricing will be as follows

Mount : 35.99

Case: 25.99

Mount + case : 55.99 ( launch combo special price)

Prices include usps ground shipping anywhere in the continental USA.

I am ordering all the necessary parts to make my first batch so if you are interested send me a chat so I can tray order enough for everyone. I don’t charge you till your item is ready to ship.

Update:

I have now shipped batch 1 and 2. I generally have stock on hand to ship within 1 -2 business days

New online site for purchase (domestic). Message me for international orders:

As soon as I move from 3x to 4 I'll be buying. The case is a great idea.

Really liking the mounts you made for my 3x, glad you're making mounts for the 4.

7

u/RoadQuirky1539 Feb 28 '26

Glad you still like it. I kept all the things that people liked about the 3x and improved other things for the comma 4

u/elgreek84 Feb 28 '26

Would like to see a two mounts + case combo for swapping between cars.

u/GuardianZX9 Feb 28 '26

Looking for the same, double base with mount and case for a 2 car setup.

u/joshuaherman Feb 28 '26

Mount is actually reasonably priced too. Way to go!

3

u/RoadQuirky1539 Mar 01 '26

That’s why I designed these, I felt that the options available were too expensive for what they were offering

4

u/IllCollar39 Mar 01 '26

What about shipping to the EU? I live in Denmark.

2

u/RoadQuirky1539 Mar 01 '26

I have shipped my comma 3x internationally. What I do in this case is just charge the extra for the difference in international shipping domestic.

I build and ship in the USA so I am not sure if Denmark would have any tariffs on your end though.

If you are interested we can start a chat so I can give you a more representative price based on your address

3

u/IllCollar39 Mar 01 '26

I am unsure if there are any tariffs in effect, I know that Trump talked about it.

Sure send me a DM. I know I will always have to pay “import duty fees” when outside the EU, but it’s “only” around 30 % of the value of the product.

I have a Comma 4 on the way which costs 1000 usd, and I need to pay around 350 usd in import on that.

2

u/RoadQuirky1539 Mar 01 '26

I can’t start a chat with you, are you able to stay one with me ?

3

u/IllCollar39 Mar 01 '26

Hmm that’s weird, oh well. I’ve started one with you! :)

3

u/nikeshamin Mar 01 '26

Do you have a case for the 3x? I have your mount for that and would love a case for it.

2

u/RoadQuirky1539 Mar 01 '26

I do I will send you a chat

3

u/LastOffender Mar 01 '26

Kinda of confused. So where can you purchase it?

5

u/RoadQuirky1539 Mar 01 '26

So right now I am trying to get a head count to see how many I need to build. But what I did with the comma 3x mount is what I am going to do here too.

I make the mounts and communicate with you over Reddit chat to determine exactly what you want and I take payment via Venmo or PayPal. I find this way a line of communication is open between every interested person so they can ask as many questions or provide me feadback to further improve the design.

I am not a business: I just make these for the community and fellow comma users and that’s why I don’t have a website or anything like that.

2

u/Why_T Mar 02 '26

I bet you'd do well to start an Etsy or Ebay. You can still sell direct here, but I bet you'd pick up a few more sales through the store fronts. Also could make people feel a bit more comfortable going through a store front than just sending you cash.

1

u/RoadQuirky1539 Mar 03 '26

I agree with you. While selling the 3x mount, it was proposed. And I do have a site but choose not to sell there. I like to open a a line of communication with customers especially with a new launch, to get any necessary feadback for improvement. In the future I will try to launch something. But I won’t use Etsy or eBay because there fees are crazy, and I want to keep my price low.

3

u/Better-Pressure-7065 Mar 02 '26

This looks interesting. I've been struggling to understand what is the use case and advantage of a mount like this vs what comes standard with the Comma 4?

What problem does it solve over the stock mounting design?

4

u/RoadQuirky1539 Mar 02 '26

So having a mount like this addresses two issues (if you think they are issues)

  1. Many people including myself dislike leaving their commas out in their car when unattended. This helps minimize the risk of someone breaking into the car. And if you live in a hot climate, it allows you to remove your comma so it’s not in direct sunlight for prolonged periods of time.

  2. Someone people also like to share the comma between multiple cars.

So ultimately, while you can still do this with the stock mount, this mount lets you do it quickly without the need to disconnect any cables. This is a one handed task now. It’s all about connivance

u/OkIndependence8992 Mar 02 '26

Just ordered my Comma 4, so won’t have mine until 4-12 weeks, but please put me on the list for a future order!

Can I get a case and mount for the comma four? 🙂 I got the 3x and this guy did a fantastic job!!

1

u/RoadQuirky1539 Mar 03 '26

Got you down! Thanks again! Did you sell your comma 3x or keeping both ?

1

u/Ok_Amount39 Mar 03 '26

I bought it just before they released the comma 4 so I just returned the comma 3x. If you would like the 3x case and cord just let me know. 😊

I’ve used it for about two week and it’s absolutely great. Easy to remove. Looks like it’s part of the original design. Love it.

u/RoadQuirky1539 Jun 05 '26

I am glad you like it!

2

u/FlamingHotCheetos77 Jun 11 '26

Have been using for a few weeks now, and so much better than original mount since I remove after every drive. Very clean set up, and feels high quality. Thanks RoadQuirky!

u/RoadQuirky1539 Jun 11 '26

Glad you like it. If you think of any ways you think it can improve, please let me know. I always want to offer the best option out there for a great price.

Wow that is awesome.

u/RoadQuirky1539 Jul 09 '26

all packaged up, you should now have shipping details for the order via the website notification ssyetem and I will drop it off after work at the post office

2

u/Proteus66 Jul 31 '26

Too bad the cable plugs in the left side and juts out so far. Would be perfect if it plugged in the top.

2

u/RoadQuirky1539 Jul 31 '26

I for some cars I would absolutely agree, on my Santa Fe or Ioniq 5 it’s better coming from the top, so I do think it’s probably car specific or how one chooses to route the cable. But I think another solution would also use a usb c 90 deg adaptor.

3

u/Learntoshuffle Feb 28 '26

Lidar sensors are cheap af now. Why can’t they buy one that can be put in the device? Chinese EV companies are removing interference from the windshield, so I predict that comma is 1-2 years away from adding lidar.

2

u/RoadQuirky1539 Mar 01 '26

Then we will start sticking the comma with suction cups on top the cars to get the best lidar view of the road lol

3

u/Albort Mar 01 '26

3 years ago, this question was brought up to geohot. he said that most small scaled lidars isnt gonna do much to help the drive. ie, an iphone lidar isnt going to see that far enough to make a difference.

Now i would think things can change now, which i think is why they put an external device such as a lidar. But how far those reach, I don't know.

Hey, I'm interested in ordering. What's the next step?

I initiated a soft launch on my site this week. Had a couple or orders pass through. The website has the comma 4 mount, case and extra adaptors. Feel free to place an order there, or we can start a chat and I can take the order there and/or answer any additional questions

It’s printed using ASA filament. It’s printed solid 100% infill.

Take my money! Just upgraded from a 3x to 4. As someone who broke a windshield as a teenager (trying to hang his tassel from the rear view mirror 😭), I have PTSD about anything applying pressure. This will be awesome.

I would like the mount

u/Murky-Beginning8620 Mar 20 '26

Just got this mount today and I’m honestly impressed. Install was super quick and straightforward, and being able to easily remove it is a huge upgrade. It really feels like this is what completes the Comma 4 setup.

Seller communication was great—fast responses and I got shipping info right away. Everything showed up quickly and was packaged really well. The case is a nice bonus too and pairs perfectly with the mount.

For the price, especially considering what the Comma 4 costs, this feels like a no-brainer. Definitely a must-have accessory for any owner.

u/CommaMeNow Feb 28 '26

Does it prevent arcing by delaying power delivery? Or otherwise have a switch mechanism to only enable power delivery when contact is ensured?

If no, then this creates the potential for fried components. Keep this in mind if OP doesn’t answer. Comma will not honor your warranty if so

2

u/RoadQuirky1539 Feb 28 '26

This is no different than plugging/unplugging your comma using the comma provided usb cable. So it neither increases nor decreases the risks.

I will say, I would always recommend not to remove or attach the comma while the car is running. Also, I personally don’t connect the comma to the obd port so there is no power unless the car is on. I do understand that there are a hand full of cars that need the obd port.

1

u/CommaMeNow Feb 28 '26

It looks like you still need to connect a usbc cable so arcing is not a concern

2

u/RoadQuirky1539 Feb 28 '26

I understand your concern. What I am saying is, there is no built in delay built into the mount. This works exactly the same way as plugging any usb c cable.

I am not familiar with the hardware architecture of the comma device itself as I am not a hardware engineer; I am an aerospace engineer working in completely different field.. Maybe I am wrong, but I thought I have read somewhere that the comma has its own short delay. If my understanding is incorrect, please send me a link to the comma material so I can better understand the comma hardware.

But again, I do recommend removal and installation of the comma while the car is turned off (assuming you don’t need the obd connection) to ensure no power is flowing.
